Military roads helped the felines domesticate about 2,000 years ago. Breakthroughs, discoveries, and DIY tips sent every weekday. Our pet dogs have been by our side for at least 20,000 years, evolving right along with us. True to their more elusive nature, the timeline of when cats domesticated is more murky. Our homespun feline friends appear to be a more recent arrival in some parts of the world, likely only arriving in Europe about 2,000 years ago.

We propose a new general Graph Adversarial Domain Adaptation (GADA) based on semantic knowledge reasoning of class structure for solving the problem of unsupervised domain adaptation (UDA) from the big data with non-shared and imbalanced classes to specified small and imbalanced applications (NI-UDA), where non-shared classes mean the label space out of the target domain. Our goal is to leverage priori hierarchy knowledge to enhance domain adversarial aligned feature representation with graph reasoning. In this paper, to address two challenges in NI-UDA, we equip adversarial domain adaptation with Hierarchy Graph Reasoning (HGR) layer and the Source Classifier Filter (SCF). For sparse classes transfer challenge, our HGR layer can aggregate local feature to hierarchy graph nodes by node prediction and enhance domain adversarial aligned feature with hierarchy graph reasoning for sparse classes. Our HGR contributes to learn direct semantic patterns for sparse classes by hierarchy attention in self-attention, non-linear mapping and graph normalization. our SCF is proposed for the challenge of knowledge sharing from non-shared data without negative transfer effect by filtering low-confidence non-shared data in HGR layer. Experiments on two benchmark datasets show our GADA methods consistently improve the state-of-the-art adversarial UDA algorithms, e.g. GADA(HGR) can greatly improve f1 of the MDD by \textbf{7.19\%} and GVB-GD by \textbf{7.89\%} respectively on imbalanced source task in Meal300 dataset.

Over the past several years, there's no doubt that artificial intelligence and robotics have pushed far beyond traditional business areas and are becoming prevalent in almost every industry, from healthcare and manufacturing to enter emerging domains including education, rehabilitation, defence and entertainment. At robotics companies across Massachusetts, the long-time science fiction film staples are becoming a reality. The co-mingling of engineering and science along with artificial intelligence have not only revolutionized the industries but also produced some truly innovative products. From welding, teaching, assembling cars or performing surgery, these limitless inventions of robots are exchanging different roles in the society. With these developments in place, TradeFlock have rounded up Top 10 Robotics Companies in USA that has an astonishing potential to transform this space.

You probably picture robots as clodhoppers: ponderous, clunky, even doddery droids that need caffeine, badly. But robots are on the brink of making giant strides. Just ask Columbia University engineering professor Hod Lipson, who writes in Nature that "young animals gallop across fields, climb trees, and immediately find their feet with grace after they fall"--and robots are set to follow suit. A new breed of speedy robots promises to eventually outdo the runners at the 2020 Tokyo Olympics. Notable cybernetic contenders include MIT's dominant Cheetah, Boston Dynamics' Petman and Handle, Michigan Robotics' MABEL, and--further afield in South Africa--the University of Cape Town's Baleka. Plus, that efficiency-geared Florida University powerhouse, the Institute for Human & Machine Cognition (IHMC), fields a smart, sensor-free biped plainly called Planar Elliptical Runner (PER).

Meet Atlas, a humanoid robot capable of crossing rough terrain and maintaining its balance on one leg even when hit from the side. These are the latest creations of Boston Dynamics, a US robotics company part-funded by the Defense Advanced Research Projects Agency (Darpa). The robots are part of Darpa's Maximum Mobility and Manipulation programme. Darpa says such robots "hold great promise for amplifying human effectiveness in defence operations". Referring to Atlas's ability to remain balanced despite being hit by a lateral weight, Noel Sharkey, professor of Artificial Intelligence and Robotics at the University of Sheffield, told the BBC: "This is an astonishing achievement... quite a remarkable feat."

Rare images of a wildcat on the brink of extinction have been caught by animal protection volunteers in Siberia. The endangered Pallas's wildcats have been hunted by poachers for their fur which can be sold on the black market to be made into mittens. Native to remote regions of southern Siberia, as well as Central Asia and China, they are seldom seen, and known for their reclusive and solitary lives. 'They are secretive and do not like to be seen, making these images rather special,' reported The Siberian Times. This cat was caught on camera a whisker away from an animal camera trap as it surveyed the scene in the Altai Nature Reserve in mountainous southern Siberia.
